| Notes: |
This image replaces a 270 minute red filtered sequence from 05/12/12/2006, for better seeing/guiding. For the first 58 subs, the sky conditions were 'clear' (no clouds), but hazy, with 70 to 85% moon riding high in the sky. Next two days of subs had some dark time, but not as good seeing. Background AUD counts were 2900 to 8000. See here for a 14.5" Newtonian image on hypered Tech Pan 2415 |
